In general, point estimates of vaccine effectiveness adjusted for patient age and month of specimen collection differed little from crude estimates (Table 2).
Two of the 13 children were started on MDR-TB treatment within one month of specimen submission, both of whom were diagnosed with MDR-TB based on the line probe assay.
Logistic regression was used to calculate odds ratios and 95% confidence intervals (CI) that were adjusted for the confounding variables of age (stratified into the age groups 0-4 years, 5-19 years, 20-49 50-64 years4 yeand and 65 years and over) and month of specimen collection.
A standard case report form was used to collect information for all persons with HUS, including demographics (age, race, sex), dates of hospitalization, month of specimen collection, antimicrobial use, results of laboratory tests for STEC and other pathogens, outcome, date of HUS diagnosis, and date of entry into the FoodNet surveillance system.
Logistic regression was used to calculate odds ratios and 95% confidence intervals (CIs) for having laboratory-confirmed pandemic (H1N1) 2009, which were adjusted for the variables of age group and month of specimen collection against the following: seasonal vaccine, monovalent vaccine, both vaccines, and any (either or both the seasonal and monovalent) vaccine.
Case-patients with sporadic C. cuniculus, C. parvum, and C. hominis infections were compared by age using the Mann-Whitney 2-sample test, by sex using the Mantel-Haenszel version of the χ test, by month of specimen submission, and by Government Office Region (England and Wales) or Health Board (Scotland) of the primary diagnostic laboratory.
Trends assessed may include number of cases reported by month, number of specimens submitted by month, percentage of influenza-positive specimens, and number and percentage of SARI and ILI cases tested.
We recorded information on patient age, isolation site, and date (month and year) of specimen collection.
Specimens were anonymized and only data on year and month of birth, sex, type of specimen and hospital/laboratory where the case was diagnosed were registered.
In museum collections we checked the collection dates of A. dumetorum specimens from the same region (n = 95) and found that the earliest registrations were in the last days of April (3 specimens), in May the largest number of specimens were collected (53), in June only 13 specimens were obtained and, finally, just three in July.
This patient had no history of underlying illness, had not been premature, and was 1 month of age at the time of specimen collection.
